My car has had the front pod conversion so I have the benefit of 4 headlights instead of the normal 2. However, when switched to mainbeam, the outer, dipped beams switch off and are replaced by the inner mains. Now I appreciate that would have been required when they only had one unit per side, but I'm keen to have all 4 come on and get the most light I can on the road at this time of the year.

My question is, is this a simple thing to cure via the control box (replacement?) or does the car use a switching relay for the headlights that would have to be re-wired?

Seeing as so many cars have this conversion, I'm sure someone knows a simple answer!!

Many thanks in advance.

I'm not sure about this but I think then 4 headlamp conversions are fitted with non-combination lamps ie. they are either dipped or main so you'll only ever get 1 per side depending on what setting.

That said I spose there's nothing to stop you wiring them up so they both come on at once, apart from failing the MOT

Why would that fail the MOT? On main beam you're allowed as many lights as you want (as long as it's an even number) -- that's why you can fit auxiliary driving lamps. The rules for new cars to get EEC type approval are different though. So, for example, if you bought a new Subaru Impreza and wanted the driving lamps in the bumper rather than the foglamps, you had to collect the new car, drive it round the block, then take it back to the dealer and they could fit them.

I have exactly the same problem, compounded by very dim lights, especially on dipped beam. My previous Griff had a light conversion and that had all 4 lights on when on main. I have been looking into this and have a cunning plan...

The way my lights are wired is that they are linked straight back to the original 3 pin socket which would have fitted onto the back of the original bulb. Clearly in the original configuration, the main beam replaces dip, when turned on. The problem with dim lights is due to the voltage drop in the wiring loom, especially with it coming all the way from the boot. I plan to install 2 relays. These will be actuated by the original wiring and power the lights via new cabling (fused, of course) directly from the battery . This should sort the dim lights. I plan to link the 2 relays with an appropriate diode so that when main beam comes on, the dip beam relay is activated, thus giving me all 4 lights on main.

The costs are minimal. Relays, fuse blocks and diodes all available from Maplins or similar for a couple of quid each. As it happens, most of my research for this fix is based upon a similar problem which early VW golfs suffer from. There is quite a bit of info on the web.

I have just bought all the gear to do this exact conversion...including the Philips Vision Plus bulbs the whole lot (inclusding relays, cable, fuses, fuse holders, connectors etc) for under £25...
